The purity of gold is expressed in karats,
It is used to measure the purity of gold alloys. One karat (or carat) is equal to 1/24 purity by mass.
The purity of gold is measured in carats. Carats are also used to measure the weight of precious stones, including diamonds. These are two quite different measurements, and two quite different uses of the same word.
A Lactometer is a little glass instrument that tests the purity of milk based on density/buoyancy and works on the principle of the specific gravity of milk. It is based on the Archemedes' principle. When we put loctometer inside the liquid it experience buoyant force(weight of displace fluid). Hence measure relative density in the given scale of loctometer. Lower the density of liquid farther, the loctometer will sink.
